HAY-STACKER.

Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed August 22. 1907 Serial No. 389.664:-

To all whom it may concern:

Be it known that I, CHRISTOPHER CHARLES DENENNY, a citizen of the United States, and resident of Felton, in the county of Clay and State of Minnesota, have invented an Improvement in Hay-Stackers, of which the following is a specification.

My invention is an improvement in hay stackers, and consists in certain novel con structions and combinations of parts hereinafter described and claimed.

Referring to the drawings forming a part hereof, Figure 1 is a side view of the improved stacker. Fig. 2 is an end view. 3 is a plan view of a portion of the fork; and Fig. 4 is a detail view partly in section of the telescoping shaft.

The present embodiment of my invention comprises a base A, composed of the side bars a, and the cross bars a, secured together in any suitable manner, the frame being provided at one end with brackets a secured to the respective side bars, and provided with bearings in which are journaled the trunnions of a roller a provided at each end with flanges a and at its center with a flanged drum a for a purpose to be hereafter described. A rope or is wound upon the drum a one of the ends of the rope being secured to the drum, and the other end passes forward through a pulley a secured to a cross bar a, and aswingletree a is attached to the free end of the rope.

At the opposite end of the base from th roller, brackets a are arranged one upon each side bar, the free ends of the brackets being connected by a cross bar a for a purpose to be presently described, and the brackets are secured to the cross bars by the screws a.

A standard B is hinged to each of the side bars of the base as at b, and the free ends of the standards are connected together by a shaft b upon which shaft are pivotally mounted by their centers, bars b the respective ends of the bars being connected together by rods 6 are provided with loops 6*, to which are at tached ropes secured to the roller a and winding thereon when the roller is rotated. The standards B normally rest upon the cross bar a before described, and when traction is exerted upon the ropes 6 it is evident that The corresponding ends of each barv the end of the bars to which the ropes are attached will be moved until they are approximately in a direct line between the shaft 6 and the roller, after which traction will be exerted upon the standards B to draw them toward the roller.

A hay fork C is connected with the base, the fork comprising the side bars 0 hinged to the rear end of the base as at c, and connected at their opposite ends by cross bars 0 0 Each of the side bars adjacent to the rearmost cross bar is provided with a loop 0 journaled in the bearing 0 secured to the side bar, the free end of the loop being connected by a link 0 with a fitting c on the opposite end of the bar 11 from the end connected with the rope 6 A plurality of horizontal fingers c are connected with the cross bars 0 c and a plurality of vertical fingers c are arranged between the cross bars, the vertical fingers being pivoted upon a rod 0 traversing the horizontal fingers, and the vertical fingers are connected together by a cross bar 0. To each end of the cross bar 0 is pivotally connected one of the sections 0 of a telescoping shaft, the other section 0 being pivoted 'to an eye bolt 0 connected with the respective side bar. The free end of the section 0 is split as at 0 the outer surface thereof being cone shaped, and a nut c is threaded on to the split portion, whereby to compress said split portion upon the inner section to retain the sections in their adjusted position. By the above described mechanism, the inclination of the vertical fingers 0'' may be varied with respect to the horizontal fingers, merely by loosening the nut and extending or contracting the telescoping shaft.

A slotted bracket 6 is secured to each of the standards B adjacent to the top thereof, and a shaft 6 extends between the brackets, the ends of the rod being received in the slots of the brackets, and each end of the rod is connected by a spring 6 with the respective standard.

In the operation of the stacker, when a sufficient amount of hay is placed on the horizontal fingers, traction is exerted on the rope a to cause the drum to rotate, whereby to wind up the ropes on the roller. As the ropes are wound up, the rear end of the bars I) are depressed as shown by dotted lines in Fig. 1, and the fork with its load is v lifted off the ground. It will be evident that the hay stacker engage with theshaft b and move it against the resistance of the springs 12 toward the upper end of the loop, as shown by dotted lines in the said position designated as II. The inertia of the fork and its load tends to move it into the position designated as III in the said figure, and the reaction of the spring will quickly jerk the fork back into the position designated as II, thus discharging the load with a jerk sufficient to clear the normally vertical fingers which, however, are now horizontal. When the fork is moved back into the position II, its inertia tends to move it back into its original position resting on the ground, thus reversing the motion of the roller and winding up the draft rope on the drum.

The standards B are connected together by suitable cross braces b and each of the links c is connected by a cross brace c" with the opposite bar W, as clearly shown in'Fig. 2. The stacker is provided with wheels a near its rear end, for convenience in moving the same from place to place.

I claim:

1. A hay stacker comprising a base, a roller journaled transversely thereof and provided at its center with a drum of greater diameter than the roller, a draft rope secured to the drum and winding thereon, a fork provided with side bars hinged to the base ad jacent to the ends of the roller, loops connected with the side bars near the free ends thereof, standards hinged to the sides of the base at the o posite end from the roller, bars pivoted by their centers to the free ends of the standards, a link connecting one end of each bar with the adjacent'loop, ropes con nected with the other-ends of the bars, and winding on the roller, a slotted bracket on the upper end of each of the standards, a shaft having its ends received in the slots of the brackets and projecting therebeyond to en age the side bars of the fork when said fork is lifted to a vertical position, a spring connecting each end of the shaft with the respective standard whereby to normally retain said shaft at the lower ends of the slots, and a stop on the base for supporting the standards when the fork is in its lowered position.

2. A hay stacker comprising a base, a roller journaled transversely thereof and provided at its center-with a drum of greater diameter than the roller, a draft rope secured to the drum and winding thereon, a fork provided with side bars hinged to the base adjacent to the ends of the roller, standards hinged to the sides of the base at the opposite end-from the roller, bars pivoted by their centers to the free ends of the standards, a'link connecting one end of each bar with the adjacent side bar of the fork, ropes con nected with the other ends of the bars and winding on the roller, a slotted bracket on the upper end of each of the standards, a shaft having its ends received in the slots'of the brackets, and projecting therebeyond to engage the side bars of the fork when said fork 1s lifted to a vertical position, a spring connecting each end of the shaft with the respective standard, whereby to normally retain said shaft at'the lower ends of the slots, and a stop on the base for supporting the standards when the fork is in its lowered position.
